Embodiment Construction

[0023] The overall hoisting method of the marine engineering module of the present invention mainly adopts floating cranes and special hanging beams. First, the large-scale modules are hoisted from the land to the barge, and the barge is used to transfer the modules to the deep water area where the main ship system to be built is moored. Ballasting, lowering the freeboard height, and then hoisting the modules from the barge to the main hull allows for the lifting of larger modules with the height of a smaller floating crane.

[0024] Such as figure 1 and 2 As shown, the structure of the special hanging beam used in the present invention includes two layers of corresponding parallel steel pipes 2 that are respectively welded and fixed into a square "lattice" structure. At the intersection of each "grid", two layers of parallel steel pipes are respectively welded and fixed on a vertical steel pipe 33, and the lower end of each vertical steel pipe 33 is fixed with a suspension r...

Abstract

The invention discloses a method used for realizing the integral lifting of marine engineering modules in the marine engineering field. After the module is constructed integrally, the invention makes use of floating cranes, barges and special crane beams to realize the integral lifting of modules on water by regulating the sea gauge of a main hull. Compared with the similar technology, the invention has the following advantages that the preparation of special crane beams can reduce the length of lifting cables so as to enhance the effective lifting height of floating cranes; and the adopting of the floating crane to lift the modules to the barges can avoid the use of a plurality of fittings used for conveying so as to reduce the cost. Simultaneously, the deep water is adopted to moor the main ship so as to ballast the main hull and reduce the height of the freeboard and then the high lifting capability of the floating crane is enhanced and the shipbuilding cost is reduced finally.

Description

technical field [0001] The invention relates to a carrying method of a large-scale assembly module in ocean engineering, and more specifically relates to a method for hoisting an engineering module on water. Background technique [0002] At present, in marine engineering, when it is necessary to hoist large modules on the main hull as a whole, a powerful floating crane is often required. The height requirements of the floating crane are very strict, and the height must be large enough. However, the rental cost of large floating cranes is very expensive. At the same time, due to the limited number of large floating cranes, it is often impossible to rent them, which greatly affects the construction period. [0003] In addition, under the prior art, the module is usually transported onto the barge by dragging onto the barge. The preliminary technical preparations for this method of towing the barge are complicated, and the material used for towing the tooling is huge and expen...
